SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 581,130, dated April20, 1897.

Application filed January 14, 1896. $erial No. 575,426. (No model.)

To all whom it may concern.-

Be it known that I, JACOB OEFINGER, a citizen of the United States, anda resident of Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inSash-Balances, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts.

This invention relates to supports and locking devices for window-sashesand the object thereof is to provide an improvement in this class ofdevices by means of which counterbalance-weights are dispensed with andwith this and other objects in view the invention consists in theconstruction, combination, and arrangement of parts hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which Figure 1 is afront view of a portion of a window-frame, showing also the upper andlower sashes mounted thereon with my improvement connected therewith;Fig. 2, a vertical section thereof, and Fig. 3 a section on the line 3 3of Fig. 2. I

In the drawings forming part of this application, A represents awindow-frame or a portion thereof, and B and C the upper and lowersashes mounted therein, and in the practice of my invention I secure tothe upper inner surface of one of the sides of the windowframe A apulley D, which is mounted in a frame at and over which is passed a cordor chain E, one end of which is secured to the upper portion of theupper sash, as shown at F, and the lower end of which is carrieddownwardly and passes through a lever or arm G, which is pivotallyconnected with the upper part of the lower sash at g by means of a plateg which is provided with standards 011 its upper surface, with whichsaid lever or arm is pivotally connected. Formed in the lower sashadjacent to said arm or lever G is a chamber or cavity H, and the outerend of said arm when taken in connection with the accompanying drawings.Whenever it is desired to raise the lower sash and lower the upper one,it is only necessary to depress the outer end of the lever or arm G andthen raise the lower sash, when the upper one will be lowered, as willbe readily understood, said upper sash being supported only by the chainor cord E, which is connected with the arm or lever G. IVhen it isdesired to again lower the lower sash and to raise the upper one, theouter end of the arm or lever G is depressed and held in the depressedposition while the lower sash is pulled down, and this operation willalso raise the upper sash, as will be readily understood.

WVith this construction itwill be apparent that the upper sash cannot belowered from the outside because of the connection of the cord or chainE with the arm or lever G, which operates in connection with the frameof the window, and the lower sash cannot'be raised without firstmanipulating the arm or lever G for the same reason, and in order toraise or lower either sash the arm or lever G must first be manipulatedas hereinbefore described. I also secure to the lower portion of theupper sash a plate K, the lower edge of which is provided with teeth orserrations k, and the object of this plate is to prevent an attempt fromthe outside to interfere with the operation of the lever or arm G, whenthe upper sash is partially lowered, by inserting the hand or armbetween said sashes.

It will thus be seen that I provide an effective lock and support forthe sashes of a windew and one which is comparatively inexpensive andwhich is well adapted to accomplish the result for which it is intended,and it is evident that changes in and modifications of the constructionherein described may be made without departing from the spirit of myinvention or sacrificing its advantages, and I therefore reserve theright to make all such alterations therein and modifications thereof asfairly come within the scope of the invention.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- The combination with a window-frame, and

vidcd with a cavity or recess, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in prcs- 15 ence of the subscribing witnesses, this 27th day ofDecember, 1805.

JACOB O'IWINGER.
